DEVICE FOR USE IN CONSTRUCTING BUILDINGS.

vide improved means for finishing the surface of the wall. I

Other objects will appear from the following description, reference being made to the drawing in which Fig. 1 is a view showing a portion of a wall in section, and showing features of my invention used in the erection of the wall.

Fig. 2 is a view showing a modification.

Fig. 3 is a perspective view of the device used in finishing the surface of the wall.

Fig. 4. is a view of the form or mold piece used in forming the corners of the walls.

Fig. 5 is a plan view of the molding apparatus and Wall showing the relative position of the various elements.

In the invention shown in Fig. 1 the vertical studding 1 of wood is supported between a lower horizontal studding 2 and an upper horizontal studding 3. The lower studding rests upon the foundation of the building or wall.

The forms for holding the concrete and shaping the wall are supported in connec: tion with the studding and comprise ver-. tical angle iron members 4 having their lower ends spaced from the lower studding 2 by tubular spacers 5. For each pair of angle irons 4 a bolt 6 is employed, the same passing through the angle iron members 4:, through the tubular spacers 5, and through the lower studding 2 and having a nut 7 screwed on the threaded end thereof to secure the parts in said position. After the concrete has been poured and has hardened, the nut 7 is removed and the bolt 6 is withdrawn, leaving the spacers 5 imbedded in the concrete.

The upper ends of the angle iron members 4 are attached to the depending arms of an inverted U-shaped bracket 8 and are held in connection with the bracket by releasable bolts 9. The bracket 8'is held in position on the upper studding 3 by bolts 10.

The mold face plates 11 are placed against the inner sides of the upright angle iron members 4, there being as many plates 11 in horizontal alinement as are necessary to make the wall of the length desired. The concrete is poured into the confined space between the plates 11 and is permitted to harden, after which the bolts 6 are released sufficiently to permit the plates to be taken out and raised above the portion of the wall that is finished to continue the work.

The plates 11 used in forming each wall are of equal height; that is the plates on one side are of the same height. as the plates on the other side.

The piping 12 is placed in position before the concrete is poured, so

that the piping will be imbedded in the concrete.

In the construction shown in Fig. 2 the angle iron holding members 13 are relatively short, being secured to the upright studding by clamping brackets 14 engaging vertical arms 15 on the angle iron members and pressing them against the vertical studding 1. After the concretein each mold space has hardened the clamps 14 are loosened and the mold formed by the plates 11 is raised to position to form another portion of the Wall. In this construction the mold face plates are supported upon projections 16 in connection with the members 13.

In forming the corners of the building the face plate shown in Fig. a may be used, the same comprising a plate bent to form the two portions 17 and 18 reinforced by angle iron reinforcement members 19 adapted to bear against adjacent upright angle iron members4. These angular face plates are of the same height as the cooperating face plates 11.

The trowel shown in Fig. 3 may be used to form smooth surfaces on the wall. As there shown the trowel comprises a pair of plates 20 held in spaced relationship by space members 21. The outer plate is formed with numerous holes 22. These devices are placed against the inner sides of the plates 11 with the holes 22 toward said plates 11. The space between these devices is filled with coarse concrete and the devices themselves are filled with finer or finishing concrete or material. When the coarse concrete fills the space to the top of the device 20, the latter, filled with the finer or finishing material, are worked back and forth and up and down and then withdrawn leaving the finer or finishing layer of material. bonded with the coarse concrete. The smootl ing or finishing material is placed between the plates 20 and passing through the holes 22 to the plates 11, so that when the trowel device is removed a finished smooth surface will be termed. The trowel device is provided with handles 22% if desired a removable core or wood or other material may be positioned vertically and the concrete poured around it. This core may then be drawn out upwardly and as the concrete sets or hardens a vertical cavity will be formed through the concrete wall Iron-1 the bottom or lower part thereof to the top. Cavities of this sort to ed in the wall render the wall drier and less subject to changes in temperature. These cores may be similar to the studs 1 and, in tact, be initially placed in the same manner as the studs 1 and slightly tapered from top to bottom to facilitate withdrawal.

In case such strengthening is needed the lower ends oi the holding members 1-3 may be strengthened by straps connected to the lower ends of said members and to the studding. The concrete will imbed the inner portions or the straps 2d and the protruding ends thereoi may be cut otl at the surface of the wall aft-er the concrete has hardened. he inner ends of the straps "may be attached to the stndding to obtain the desired rigidity.

I am aware that the invention may be vared in equivalent particulars without departure from the nature and principle there of, and Ido not restrict myself tin-essentially but what I claim and desire to secure by Letters Patentis 1. A. device for erecting a concrete wall having upright stndding imbeddcd in the wall, comprising two series of upright members located respectively on opposite sides of the studding, connections uniting the lower ends and the upper ends of the members of one series with the corresponding members of the other series of upright memarass? hers, and removable plates bearing against the inner sides ot' the members of each series and forming a space between them to receive the concrete.

2. A device for forming a concrete wall having lower and upright studding members imbedded in the concrete, comprising a series of vertical members at each side of the studding members, releasable connections uniting the lower ends of said series of up right members and passing through the horizontal studdin releasable brackets uniting the upper ends oi: said series of upright members, and metallic plates bearing against the inner side of said upright mem bers and 't'orming a space between them to receive the concrete,

3. A device for it'orn'iing a concrete Wall having horizontal and upright studding members imbedded in the concrete, comprising a series of vertical members at each side of the studdingdnembers, releasable conn tions uniting the lower ends of said. series of upright members and pass ng through the horizontal studding, releasable brackets uniting the upper ends of said series of up right members, metallic plates bearing against the inner side of said upright methibers and forming a space between them to receive the concrete, and removable hollow devices for placing surfacing material be tween said plates and the concrete;

l. A device for forming a concrete wall having horizontal and upright studding members imbedded in the concrete, comprising a series of vertical members at each sine of the stndding members, releasable connections uniting the lower ends of said series ot upright members and passing through the horizontal studding, relea, able brackets uniting the upper ends of said ries of upright nien'ibcrs, metallic plates bearing against the inner side ol? said upright members and torn'iing a space between them to receive the concrete, and means tor applying asmoothing finishing material to the surface of t 1e concrete before said plates have been removed,
